The steps in 5.2. are not updated and are still as there is still necessary to download and unzip mod_cluster natives from EAP distribution, which is wrong, because they are already shipped with EWS.
Also in in 6.2. Configure a Load-balancing Proxy Using the HTTP Connector sentence about installing modules:
"Install JBoss HTTP Connector modules. Refer to Chapter 5, Proxy Server Components for details"
Also it irrelevant because mod_cluster modules are already installed in EWS 2.0 httpd and tomcats

Actually the whole Section 5.2 is unneeded as mod_cluster is already configured correctly in EWS httpd, thereby there should be just some note regarding it is already preconfigured and next section already points how to update the configuration.

* Removed line about referring to EAP Install Guide to find mod_cluster natives. (ignore, third point removed need for this)
* Updated 6.2 to state that the only prerequisite for the procedure is an installation of EWS 2.0.
* Removed contents of 5.2, replaced with note as in comment#4.
